类 MapDataSerializer

java.lang.Object

org.apache.flink.api.common.typeutils.TypeSerializer<org.apache.flink.table.data.MapData>

org.apache.flink.table.runtime.typeutils.MapDataSerializer

org.apache.flink.table.runtime.typeutils.serializers.python.MapDataSerializer

所有已实现的接口:

Serializable

@Internal
public class MapDataSerializer
extends org.apache.flink.table.runtime.typeutils.MapDataSerializer

A TypeSerializer for MapData. It should be noted that the header will not be encoded. Currently Python doesn't support BinaryMapData natively, so we can't use BaseArraySerializer directly.
